"doesn't that include Greenland?"
....not in my geography book...

"America" is a funny name, which sort of got applied and used before it got well settled. It 'sort of' refers to most of the Western Hemisphere, but usually just to the USA, which is the only country which incorporated it. I'd like to have been in the discussion groups trying to decide on a group name for 13 odd states trying to creat some sort of 'union'....I believe "Columbia" was seriously considered before it was taken.
